Reciprocating compressors

Due to their simple structure and low operating costs, reciprocating compressors have been used for many years where there is no need for compressed air continuously. It would be best if it was 50:50 (work - rest) in the shortest possible cycles.

These can be small industrial plants, service workshops, car or tire services, or, for example, gas stations. Often, reciprocating compressors are also used by DIY enthusiasts.

The greatest advantage of this type of compressors is mobility, durability, price and low operating costs.
It should also be taken into account that due to the principle of operation of a reciprocating compressor, a natural pulsation of pressure and flow rate occurs in a pneumatic system.

The high noise level of this type of compressors is also important. In order to reduce the noise level, there are also versions with a soundproofing housing.

Due to the type of lubrication, compressors are divided into oil (the most common) and oil-free.

Oil-free compressors

Instead of oil lubricating the crank-piston system, these compressors have piston sealing rings made of PTFE - i.e. Teflon, which does not require additional lubrication. Therefore, we get air free from oil particles - which is their unquestionable advantage.

Oil-free compressors are used where particularly high air quality is required, such as the food industry, pharmaceutical industry or medical applications, e.g. in dental units or in the water treatment process.

Our offer includes reciprocating compressors from manufacturers such as Atlas Copco, the German company BOGE and Italian compressors owned by our brand - Pneumatig.

The basic group of Atlas Copco oil-free compressors is the AH Automan series with max.
operating pressure of 8 bar. On the other hand, professional applications include the LFx and LF series with max. pressure of 10 bar.

As for the second manufacturer, BOGE is the ASO / BSO and K series, which are considered to be the most durable oil-free piston compressors available on the market.

Oil compressors

The reciprocating compressor is used wherever air consumption is less than approx. 800 l / min and it is possible to allow the compressor to run intermittently.

It is not without significance that such a compressor generates quite bothersome noise, and not everywhere can be afforded it, which is why we offer optionally soundproofed versions (soundproof housing - for some models).

Due to the structure of the compression stage (compressor pump), it can be divided into:

  • one piston
  • 2-piston compressor
  • two-piston with two compression stages
  • 3 piston compressors

However, due to the type of drive transmission, we can divide it into a direct drive, where the motor is integrated directly with the pump, or with a belt drive.

Integrated (direct) drive is available in single-piston or 2-piston compressors, such as Atlas Copco LE, LT series. They are slow-speed compressors, which translates into longer durability of these devices.

Single piston compressors are usually small oil compressors with a 6, 9, 24, 50 l tank, with a supply voltage of 230V / 1Ph / 50HZ

On the other hand, two-piston compressors are available with a tank from 24 l (compressors in a V system) through 50, 100, 150, 200, 270, 1000 l, with a supply voltage of 230V / 1Ph / 50Hz (with lower engine power) and 400V / 50Hz / 3Ph (the vast majority).

Single piston compressors can generate a pressure of max. 8 or 10 bar (AF Atlas Copco series), while two piston 10, 15 or even 30 bar in the case of Atlas Copco compressors of the LT series or BOGE compressors.
A separate group of high-pressure reciprocating compressors are compressors for the starting of axial engines, they are equipped and manufactured differently from the basic versions, and have DNV or Lloyds Register approvals.

The power range of the most commonly used motors is from 1.1 kW to 7.5 kW and even 15 kW.

Reciprocating compressors frequently asked questions

    • What is the actual (effective) capacity of the compressor?

      Many manufacturers give this value as a theoretical value, i.e. as the compressor gets from the environment (on the suction side). On the other hand, the actual amount of air that the compressor is able to produce is lower by approx. 30% -40% and this should be taken into account when selecting the device.
    • What determines the efficiency of a reciprocating compressor?

      It depends on two factors, namely: cylinder size, which determines its volume, and compression ratio, i.e. the ratio of pressures being the proper stroke of the piston, which is the ratio of discharge pressure to suction pressure. It is very important to maintain the tightness between the piston and the cylinder surface, which directly affects the efficiency of the compressor. Ambient conditions: atmospheric pressure, temperature of sucked in air and its humidity
